Execute reviewed testimonial tasks

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=true, but the description adds failure semantics the agent could not otherwise know: stop on first failure, return known results plus failed index and unattempted indices, and explicitly no retries, no rollback, no implicit continuation. That is precisely the operational context needed before firing a destructive batch.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tight sentences with no filler; the scope, the pre-request validation and the failure contract are front-loaded in that order. It is telegraphic to the point that the opening clause is a noun fragment rather than a sentence, which slightly hurts readability but wastes nothing.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive, non-idempotent batch tool with no output schema, the description supplies the crucial failure/return-shape contract (known results, failed index, unattempted indices) and rules out rollback. It does not spell out the side effect on the target system (published testimonials vs. dispatched emails) or the meaning of the account binding, which the schema covers only partially.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so tasks, account, confirm and review_sha256 are already documented in the schema. The description reinforces the ordering and 1-20 bound of tasks and the hash-verification requirement for review_sha256, but adds no syntax or format detail beyond what the schema states, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names the exact resource (testimonial tasks) and its scope (one-to-twenty ordered text/video import/email operations), which separates it from the single-task siblings submit_text_testimonial, submit_video_testimonial and send_testimonial_request. The verb is implicit (the fragment 'Confirmed ... tasks' never says 'executes'), but the title and the batching scope make the intent unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It implies the correct workflow (prevalidate everything, verify the exact hash before the first request), which only makes sense after a preview, and 'Confirmed' implies prior review. However, it never names preview_testimonial_batch as the required predecessor or states when to use this batch tool versus the individual submit tools, leaving the routing to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
